3105 aluminum sheet available products
We offer 3105 aluminum sheet in a full range of common tempers.
We supply in both sheet and coil, with slitting, cut-to-length leveling, and custom cutting to match your process route.
This helps you place an order faster and start production with less extra handling.
-
3105 Mill Finish Sheet Coil
Designed for post-painting, stamping and bending, roll forming, and general sheet metal fabrication.
3105 is a non-heat-treatable alloy. It offers stable corrosion resistance, formability, and weldability for continuous processing and volume supply.
If you're unsure whether to choose H14 or H24, tell us your forming method (bending / roll forming / stamping) and appearance needs. We'll recommend a practical option used by engineers.
-
3105 Pre-Painted Sheet Coil
Built for exterior cladding and appearance-part purchasing, such as building facades/envelopes, trailer and body skin, signage, and decorative panels.
Chalco supplies factory pre-coated / coil-coated material. After receipt, you can slit, level cut-to-length, roll form, or bend right away, reducing repainting time and batch-to-batch risk.
Coating systems can be matched to your environment (indoor/outdoor and weathering level). PVDF / PE options are available, with color matching by RAL/NCS codes or customer samples. This helps reduce color shift, rework, and project risk.
-
3105 Embossed Stucco Sheet Coil
For insulation jacketing on pipes, tanks, vessels, and equipment insulation systems.
Embossed surfaces (such as stucco) resist scuffs during transport and installation. They also add panel stiffness and reduce visible waviness, making them better for outdoor job sites.
For project acceptance, please state the surface type, service environment, and any extra requirements in your RFQ (such as moisture barrier or coating).
-
3105 Tread Pattern Sheet
For steps, platforms, walkways, vehicle flooring, and protective panels where anti-slip and wear resistance matter.
If you need 3105 tread plate, specify the pattern type (five-bar / diamond, etc.), thickness, size, application, and load/anti-slip requirements in your RFQ.
We will confirm the workable specification and processing route accordingly.
Send us your application, size/temper, and whether you need pre-painted material (color/coating system). We can quote quickly and accurately.
If you need help selecting, tell us your use case and we'll match the right parameter combination for you.

3105 pre-painted aluminum sheet color and coating selection
For exterior cladding and appearance-part projects, what drives acceptance and rework cost is often not thickness.
It's color batch variation and coating batch variation.
That's why we recommend clearly specifying the color system and coating requirements when purchasing 3105 pre-painted aluminum sheet.
This helps keep batch consistency and delivery under control.
Popular color examples
We offer multiple standard colors for fast purchasing needs in common uses such as signage, trailer side panels, and wall panels.
We have shown color images on this page, but the actual appearance may vary with lighting, display settings, and surface gloss.
For appearance-critical acceptance, we recommend using a physical sample or an official color code as the final reference.
Custom colors available
We also support custom colors matched to your brand or project samples.
This helps you keep a consistent look and stronger visual identity.
For easier internal approval and acceptance, we can customize per your project requirements:
- Coating system: PVDF / PE (or customer-specified system)
- Color system: RAL / NCS / customer sample (color control by standard code or by sample, with ΔE requirement if needed)
- Coating side: single-side or double-side coating; whether a back-side coat is required
- Protective film: optional for transport/forming, and whether embossed/orange peel or other surface textures are required
If you want us to recommend the most suitable PVDF/PE option or confirm color matching, please send your color code or sample requirements.
We will suggest a workable coating and delivery plan based on your application.

Contact Us3105 aluminum sheet selection tips:
- For pre-painted projects, specify single-side or double-side coating, gloss level, and protective film. Make appearance consistency part of your acceptance criteria.
- Tell us your roll forming / bending / stamping process and key bend requirements. We will match the right temper and size to reduce springback and cracking risk.
- For projects with frequent lifting, installation, or job-site rubbing, we recommend protective film to reduce rework on appearance.
- If riveting or bonding is involved, please tell us early. Joining method and contact materials affect surface recommendations and delivery details.
- Choose thickness based on panel span, installation strength, and service environment. Avoid "too thin" distortion or "too thick" cost and handling burden.
- Welding or flame cutting should be evaluated. For double-side coated products, run a process check and protection plan to prevent heat damage and appearance issues.
Just share your application and key parameters.
We will match the right 3105 product type and delivery plan, and provide an approval- and acceptance-ready document package.
This keeps selection accurate, delivery controllable, and your project moving smoothly.
Features of 3105 aluminum sheet
- Pre-painted wear-resistant surface: the coating resists abrasion and scratching, ideal for appearance-sensitive projects during transport, installation, and fabrication.
- Lightweight: aluminum has low density, making handling and installation easier while reducing overall weight.
- Corrosion resistant: works in many indoor and outdoor environments, especially for cladding, enclosures, and general exterior use.
- Easy to form and fabricate: good ductility for bending, roll forming, and stamping.
- Good welding compatibility: the base metal offers solid weldability.
- Non-heat-treatable alloy: 3105 cannot be heat treated to increase strength; strength is mainly matched by work hardening (temper).

FAQ (frequently asked questions)
What is AA3105 aluminum?
AA3105 is a non-heat-treatable aluminum alloy. It is widely used for sheet/coil, pre-painted base metal, and architectural panels.
Common equivalents include EN AW-3105 and JIS A3105P.
What is the difference between 3105 and 5052 aluminum?
5052 is an Al-Mg alloy. It usually offers higher strength and better corrosion resistance in marine environments, so it is preferred for structural and marine use.
3105 is more focused on forming and coating applications such as pre-painted sheet, exterior cladding, and roll forming, with a more cost- and supply-friendly product form.
What is the difference between 3003 and 3105 aluminum?
3003 is a classic Al-Mn general-purpose sheet alloy with very broad usage.
3105 adds a small amount of Mg on the Al-Mn base, so strength is typically slightly higher. It is often chosen for pre-painted/architectural sheet and roll-formed products.
What are the characteristics of 3105 H24 aluminum?
H24 is strain-hardened and then stabilized. It balances strength with improved forming stability.
It is commonly used for sheet and coil that require bending or roll forming, where reduced cracking and springback risk matters.
